The 3-D "Captain America" film starring Chris Evans and Scarlett Johannson cost roughly $170 million to make, and has earned $303.3 million worldwide so far.

The first Captain America film, "Captain America: The First Avenger," made $65 million in its opening weekend in 2011.

Experts said the bump in revenue might portend a big summer for movies overall. Because Captain America is one member of The Avengers — whose 2012 movie garnered $623 million — they also theorized that the success of that film, as well as each member's individual films, has buoyed the entire constellation of Avengers-related Marvel movies.

"Captain America" sped past "Noah," the Bible-based movie starring Russell Crowe that opened last week. "Noah" has earned $72 million total thus far. It also beat out Wes Anderson's "The Grand Budapest Hotel" which has a domestic total of $33 million.
